PAPER-MAKING MACHINERY.

- Application filed March 12, 1925. Serial No. 15,017.

This invention relates to paper making machinery, and more particularlyto that v portion of paper making machinery which hasto do with thefeeding of the paper mak-. ing stock upon the forming part of themachine. Y

Onev of the principal objects of the 1nvention is to provide a mechanismof this character which is constructed for easy ad uStment to givesuitable control of the flow of the stock from the flow box to the wire.

Another object of the invention is to provide mechanism of thischaracter which is ca able of local adjustment, in addition to adustment as I operating irre ularities, and to thereby give great nicetycontrol of the flow of stock.

Another object ofthe invention is to provide a device of this characterwhich may be readily cleaned, and which permits of ready moving of thebreast roll, as for the purpose of changing the wire, without thenecessity of disassembling the device.

Other objects and advantages of the 1nvention will be apparent from thedescrip- 'tion set out below when taken in connection with theaccompanying drawing.

In the drawing in which like characters of reference designate likeparts throughout the several views thereof- 'Fig. 1 is a view inelevation of a embodying the invention, the view bei direction oppositeto the direction of flow the stock; Fig. 2 is a side elevation of thedevice shown in Fig. 1;

Fig. 3 is a side elevation of the device w th certain of the 'partselevated into inoperative position to permit of removal of the breastroll; and

Fig. 4. is an enlarged detail view, in side elevation of the flowcontrolling mechanism, with parts broken away to more clearly illustratethe features of construction.

As showing a preferred embodiment the invention is illustrated inconnection with a Fonrdrinier type of paper making machine. In a machineof this type the pulp, or other fibrous material, suspended in water, issupplied to a flow box, whence it is fed through a suitable opening,at-the desired rate, across a flow directing apron upon a which may ormay not be given a transverse oscillatory motion, this wire beingendless device ng in a and suspended upon two rotatable rolls, the

a whole, to compensate for' traveling wire,

roll at the fiow box or inlet end being called the breast roll, and therollat the other or outlet end of the wire being generally called thecouch roll.

In the drawing the flow-box is illustrated diagrammatically by thenumeral 10, this flow box having suitable supporting frame work 11associated therewith. Opening through the flow box adjacent the inletside thereofis an outlet 12 through which the stock flows from the flowbox and is uniform- 1y distributed upon the wire. Associated with thisopening is an apron 15 which is pivotally mounted upon the framework 11or some other fixed part ofthe mechanism, in

association with the outlet 12, by means of suitable pivots 16 arrangedat each end thereof. A stop member 17 is suitably mounted I upon theframe work to limit the downward movement of the apron. This apron isextended a suflicient distance to overlie the breast roll '18, which isrotatably mounted and constructed in any suitable conventional manner.This breast roll carries a wire 20, and it will be noted that the apronoverhangs the breast roll such a distance that its free edge u liessubstantially in a perpendicular plane passing through the axis of thebreast roll. The apron is cut away-at its forward or inlet edge, asshown at 21 to correspond to the curvature of the breast roll and thewire carried thereby.

In practice papers of many different grades will be made atdiflj'erenttimes upon a single machine. And a given kind of paper will be made in anumber of different weights or thicknesses. WVhere it is desired to varythe thickness or weight of paper this is accomplished by properlycontrolling the quantity of stock which is flowed, per unit of time,upon the wire, this practice being too well recognized to need anydiscussion. In order to control the rate of flow of the stock upon thewire means is provided for varying the effective opening through whichthe stock flows from the flow box to the wire. This means is in thetrade usually referred to as an inlet, and wherever the word inlet isused herein it is meant to designate that mechanism associated with theflow box which controls the rate of flow of the stock from the flow boxto the wire, and includes among other elements the apron, and a lipmember designated generally by the numeral 30 which is adjustable withrespect to the llU apron so that the effective opening betweenthe lipmember and the apron may be varied as desired. 7

As shown the lipmember 30 comprises an upper plate 31. This plate isprovided along its rear edge with an enlargement which is substantiallycircular in cross section th1s enlarged portion at each of its oppositeends being provided with an extension in the nature ofa stub shaft 34which is journalled 1n the frame 11. 'Mounted 'within ,the outlet themember 40 serving to support the enlargement 33 throughout its length.Preferably the enlargement 33 and the recessed edge of the member areconstructed to give a sliding fit as the members rotate relative to eachother. In order to assist in re taining the enlargement in place Withinthe recessed edge'of the plate 40 a retaining plate 41 is preferablybolted upon the upper face of the plate 40 this retaining plate beingextended to overhang the enlargement 33 and thus retain it in ositionduring operation.

The plate mem er 31 is provided intermediate its widthwith a shoulderhaving a circular recess 45 which extends there-"across. Mounted in thisrecess is a-cylindrical enlargement46, carried by'the'rear edge of theflexible plate 47, the front edge of which constitutes the effectivefront edge ofthe lip member. A retaining plate 48 is bolted to i thisshoulder, this plate having a recess 43 V therein adapted to registerwith, and be .complementary to, the recess 45, plate 31 and theretaining plate 48 thus functioning to-* gether to provide a recessreceiving the enlargement '46. Adjacent its front edge, the flexibleplate 47 has attached thereto, at suitable intervals, socket members 50which are attached thereto in any suitable way. These members are shownin'the drawing as being riveted to the plate 47 it being of courseobvious that after attachment the ends of the rivets extending throughthe plate 47 would be dressed down to provide a smooth surface, as theexistence of irregularities or projections upon the lower face of theflex ible plate 47 would result in the accumulation of stock,orimpurities, during operation of the device andsuch accumulation wouldin turn tend to make irregular the effective vertical opening throughthe inlet. If desired these socket members 50 may be brazed orsoldercdor attached in any other desired manner to the flexible )late. Thisflexible plate may be of any suitable flexible material, but brassconstitutesa very satisfactory material, since it is suflicientlyflexible, and may be readily deformed, and at the same time is'notsubject to corrosion in the presence of water which is inevitablypresent in paper making'machines. Each of the socket members has.positioned therein, when the device is'assembled, the head 52 of anadjusting bolt 53, which bolt is threadedly mounted within a bushing54,this bushing being in turn threadedly mounted within a suitablepassage in theupper plate 31. The adjusting bolt 53 and the bushing .54are each provided with suitable hand wheels or the like, 55, for use inmanipulation thereof. After the adjusting bolts are positioned to givedesired-warping or local adjustment of the flexible plate, the bushings54 are manipulated to bring the lower end" into frictional engagementwith the upper face of the socket member to lock the'device in thedesired adjusted position.

During the paper'making operation impurities tend to collect within theinlet, especially where hard water,that is water having a considerablequantity of chemicals 1n SOlutlOD there1n are used. And such collectedimpurities will often materially vary the effective opening through theinlet. In order that the paper produced may be uniform'throughout, itisnecessary that substantially-even distribution of the stock over thewireshall'be secured. For if a greater quantlty of stock is flowed to oneportion of the wire than to another the paper will be thicker where thisgreater quantity of stock is flowed than it will be at the place where alesser quantity of stock is flowed. Any material local variation in theeffective opening through the inlet, therefore, will result in unevendistribution and non-uniformity in the paper. in described thisnon-uniformityof flow may be prevented. For by the adjusting bolts 53plate 47 may be locally adjusted or warped to give a vertical openingthat will give a uniform rate of flow across the entire inlet. Thiswarping of the flexible plate 47 is shown in Fig. 1, greatly inexaggeration, in order to more readily disclose this feature of theinvention.

It is tobc understood, of course, that in warping By means of theapparatus hereproperly manipulatinm the edge of the flexiblz Itis to benotedthat the joint between the enlargement 33 andthe plate 40 is suchthat whatever ma be the positioning of the lip member t e lower surfaceof the Lesaaee joint between the flexible plate L7 and the supportingmember 31.

Foreiiecting adjustment of the lip membar as a whole one of the pivotshafts 34, extends entirely through the frame 11 and is provided at itsouter end with a gear 60, preferably a worm gearotbrass or'the like.

' Qooperatmg with this worm gear 60 IS a worm pinion 61, mounted upon asuitable shaft 62, which is rotatably supported by the l'rame' 11, thisshaft having a hand wheel 63 upon the upper end thereof. By propermanipulation of the hand wheel rotary motion may be imparted to thepivot shaft 34' to swing the lip member up or down as desired. In orderto assist in operation of the machine, in the changing of the effectiveopening through the inlet, the gear is provided on its outer face withsuitable indicating marks 65, a pointer. 66 being attached adf'acent thegear so. that by means of 'suitab e indicating characteristics anydesired positioning of the lip member to sepuic'le a given rate of flowof the stock may be As is well known the length of life of the wireswhich are used in paper making machines is limited, and in usualpractice these wires must be chan ed about every ten days to two weeks.In c angmg thewire, which is endless, it is of course necessary to somove the breast roll and the couch roll rela-" tive to each other thatafter the old wire is removed, a new wire may be readily slipped inplace over these two rolls, after which the breast roll is replaced inits normal operating position. And in many paper making machines thebreast roll is so mounted that it must be lifted bodily upward inchanging the wire. The apparatus forming the subject matter of thisinventionis particularly designed to facilitate this changing of thewire. In noving the breast roll to change the wire it is not necessaryto dismantle the inlet as is the case with other :forms of inlets known,but. the top member and the apron may be swung upwardly about theirpivot mountings, breast roll, so that that roll may be readily removed.This upward position of the apron and the top member is illustrated inFig. 3. When in this elevated position cleaning of the apron and of theflexible plate 47 may be readily effected.

in order to facilitate this movement means is provided forinterconnecting the lip member and the apron so that by proper maniulation of the hand wheel 63 the lip mem er may be swung upwardly intoinoperative out of the path of the I scribed, the combination with aflow box,

position, the apron member being concomitantly moved upon its mounting.-This con-- necting means is preferabl detachable so that it may bedisconnecte when the inlet is in operative position to permit of freead; 7 justment of the lip member without vary ing the positioning of theapron memberin" any way. A very satisfactory form of attaching means isthat shown in Fi 3 of the drawing which consists of a chain 70, the

end links of which are connected to the plate 31 and theapron 15,respectively, by means of bolts or screws. If desired the end links, ofthe chain ma be formed so that they may be readily s ippe'd on or offthe screws 71, or the device may be so arranged that the chain and thescrews are entirely re moved from the inlet, by unscrewing the screws. 7

As shown in Figs. 1 and 2 the undesirable escape of the stock throughthe end of the inlet is prevented bymeans of a plate 75, which is boltedto the apron and snugly fits against the end of the lip member toprevent the escape of the stock between the plate'and the lip member.
